Looking at the weather in early November in Jiangxi, the precipitation is less and the temperature is lower. It is expected that there will be no obvious rainfall in Jiangxi in mid-November. From the 13th, the province will welcome a strong wind and cool weather. Linyi Fertilizer Network Copyright
According to the latest meteorological data, in the first ten days of November, most of Jiangxi had no rain, and only 1 to 2 mm of precipitation occurred in the southwestern part of the river. The average temperature in the province was 15.2 °C, which was 1.3 °C lower than the same period of the previous year; November 5 On the 7th, there was continuous foggy weather in the province.

The Jiangxi Meteorological Observatory predicts that there will be no significant precipitation in Jiangxi Province in mid-November. From November 11 to 12, Jiangxi mainly consists of sunny to cloudy weather. From the 13th, due to the cold air in the north and south, the province has increased cloud cover and increased wind power. The gusts of rivers and lakes and plain valleys have reached 6 to 7 levels. The temperature drops and the process cools down by 2 to 6 °C. Linyi Fertilizer Network Copyright
Experts reminded that in the middle of November, Jiangxi was dry and dry, and the forest fire risk meteorological grade was high. All localities should continue to do forest fire prevention work, residents should pay attention to fire safety; during the cold air impact, water and land transportation, high-altitude operations should pay attention to safety, billboards, temporary Reinforcement measures should be taken in advance for the structures, and urban and rural residents should pay attention to the timely addition of clothing to prevent diseases such as colds. After the cold air has passed, it is prone to foggy weather in some areas. Please pay attention to transportation safety. Linyi Fertilizer Network Copyright
In addition, due to the continuous lack of rain in Jiangxi, the soil moisture of farmland has decreased significantly, and farmland crops need to be strengthened. Experts suggest that transplanting rapeseed should use the recent sunny weather to complete the transplanting task. The lived field is used for cultivating loose soil and soil tillage; the shed plant is used to reinforce the scaffolding to prevent the wind from collapsing; the citrus park is harvested in time, preventing The wind caused the fruit drop.

Zinc Selenide CO2 Laser Lens
The transmission range of Zinc Selenide ZnSe-CVD is 0.5 - 20 µm.
ZnSe CVD used for high power CO2 laser optics at 10.6µm, for protective optics windows or optical elements in FLIR (forward looking infrared) thermal imaging equipment, optics for medical and industrial applications (optical plane parallel windows (plates, disks, blanks), wedged windows, optical meniscus, spherical and cylindrical lenses, prisms, resonator mirrors of CO2 laser).
The refractive index is near 2.4. Zinc Selenide has a very low absorbtion coefficient and is used extensively for high power infrared laser optic. It is non-hygroscopic.
Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined.
Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
